Watch

Webhook alerts for up to 5 tokens on Base, Ethereum, Arbitrum, Optimism, Polygon or Solana for 7 days: we re-check each about hourly and POST a signed JSON alert to your https webhook when its risk score or reasons, owner or authorities, or liquidity (10%+) change, optionally price. Returns an id and an HMAC secret; GET /watch/<id> is free. Renew with {id}. Rules-based, not advice.
